To all whom 'it moy concern:

Be it'known that I, SAMUEL M. BROWN, a

subject' of the King of Great Britain, resid? ingat 327 High road, lVood Green, in the "county 'of Middlesex, England, have in-4 vented certain new and useful Improvements -in VVheelsior Road-Vehicles, lot which the following is a specification.

This invention relates tovehicle wheels of the typein which an 'elastic tire is provided with a sectional wearing tread, the sections 'of whicli'are retained inl position by -a system ofspring connections.

lIn the accompanying drawings, FigureV l is across section taken on the line` 1 --1-1 ot Fig. 2; Fig. 2 is a side elevation f part of wheel constructed accordino` to my invention; and Fig. 3 is a plan of Fig. 2. i

The method of attaching the metal covering'is by the follorwing means, vriz., with the bolts L andthe springs. a all around on eachsid`e of the pneumatic tire c passed through -or secured to the protruding rim d on each 'side ot the outer metal covering (Zand fas-- tened to the protruding parts of the 'rim e in which `the pneumatic tire o is fixed, t'. e., the

rim which forms the bed of the nieuinatic tire ;l

the nietal sprinv's a, if used, eingfixed by means ofthe bote b between the outer metal cover Il' and the inner rime (or rim in which the spokes of the wheels are fixed). The bolts I) are fixediirinly by means ot nuts, or

braced in the outer cover ot metal rl, but

allowed free play where they run through the flange c of the inner rini c, so that the springs and bolts hare tree pla;v to move up or down according to -the pressure on the pneumatic tire c that is placed inlbetween the two coverings of inetahviz., the outer meta-l cover cl and the inner rim c. The

l outer metal coi'er is lined inside with eltorany other soft material tto prevent friction 'on the pneumatic tire o. The outer corer of metal (l is divided in'to :tour or more parts,

and joined together by means of pieces of lea-ther or other flexible material y, so that the outer covering of metal when thewheel is running can be pressed on to the inner pneumatic tire c wit-hout bending the outer metal cover.

-The manner in which the sections of the outer' metal cover.. a. are connected is bymeans of leather, rubber, or Vlike material fi being 'stuck or fastened underneath the ends of each nietal section. This is to prevent dirtgetting through to the inner pneumatic tire between the sections. There are oblique apertures madein the outer metal ,cover (l,

t'lirough'wliich solid' pieces or studs of rubber f or like material project from within, and which studs have wide basesg to prevent-them from slipping through the holes l and which project so that thewheels run on the projecting. studs or pieces of rubber, or like material f instead, of on 'the metal cover d. These studs or pieces f may be fixed to the inside of the metal cover d by inans ot a sticky.. adherent or said vpiecesfcan be placed in their proper position without the use/.of such adherent, for the iessure of the outer metal vcover lento-t e inner pneumatic tire c is sutiicient v to keep them in p0- Asition when the pneumatic tire is properly inflated. l 'A Figure 1 represents a cross section of the tire showing the springs a. and the bolts b at each side of the pneumatic tirec within the outer metal' cover d, and the inner rim e, to which the spokes .are attached, also an' outer'inetal cover d, with rubberor other material as studs j', fixed therethrough with the enlarged base g ofl the studs inside of the outer metalI cover d, to which they are stuck or fixed. The springs-u can be dispensed with lfit-will.

FiO'. shows a side'elevation of parto-f the tire, with the bolts Y), the nuts j and the springs a which hold the sections ofthe outer metal cover (Z to the inner rim e, in which the spokes are tixed. Studs f of rubberor other material are stuck or fixed through the outer nietal cover The springs l can be dispensed with at will.

Fig. 3 is a plan oit the outer metal cover d, showing the divisions/1, of the same, and the nuts j, and the studs' fof rubber or other material. This is the outer portion of the tire which will come intocontact with thc road.

Having thus Jfully described my invention, what I claim and desire to secure by Letters lPatent is l. A wheel torroad vehicles (.'oinprisi'ng a rim having lateral flanges, a pneumatictire seated in the rim, an outer metal cover made in sections connected together by flexible material. lateral flanges on each section, bolts securing said sectionflanges to the rim flanges, the metal cover sections having apertures disposed obliquellvT to the direction of 110 CTR travel,v and resilient blocks with enlarged bases-it-ted 1n said apertures 1n the mannerset forth. v

AA wheel .for road vehlcles comprising a' rim having lateral flanges, a pneumatic tire Seated in the rim, an outer metal cover made in sections `connected together by l flexible material., lateral flanges on each section, bolts Securing said section Hanges to the rim ianges. springs'mounted on said'bolts and bearing on saidfianges, the metal cover sections having apertures therein disposed obliqely to the. direction of travel, and resilieut blocks With yenlarged bases fitted inn- 15 said apertures with their bases resting on a lining of felt Withinl the' outer metal cover l and bearmg on the pneumatic tire, substantially as described.
